VULCANIZERL masses;

Specification of Letters Patent.

Patented Sept. 24, 1912.

Application filed June 29, 1912. Serial No. 706,717.

To. all whom it may concern Be it known that I, EDWIN C. MCGRAW, a citizen of the United States, residing at East Palestine, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Vulcanizers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to which it appcrtains to make and use the same.

My invention relates to a vulcanizing apparatus especially adapted for applying to rubber tires and tubes. its object is to provide a simple and cheap apparatus suitable either for the road or shop, and which will require no skill to use and involve no regulation beyond the simple indication of the amount of fuel to be consumed. To accomplish this object- I have invented an open self-regulated fluent fuel heater which may be used in either vertical, horizontal or intermediate positions.

In the accompanying drawings,-l*igure lis a perspective View of my vulcanizcr in the form adapted to repair a puncture or small tears or cuts in a tube or tire; Fig. 2 is a substantially central vertical section with the tube and patch in place being repaired; and Fig. 3 a slightly enlarged front elevation indicating the "nlcanizcr attached to a wheel for repairing a tire.

In the drawings 5 represents a base, in the form ill ustated a circular-shaped plate with extending Wings (3 on each side. From each of these wings rises a threaded post 7.

8 is a receptacle preferably somewhat heavier at. the bottom of the outer wall than at the top, asindicatcd at 9, in big. 2, and having the bottom slightly concavcd on the lower surface for the purpose of fitting a patch, as illustrated in Fig. i

11 represents a web-strengthenod wing extendingfrom each side of the receptacle 8, each wing having at the end a knuckle 12 with a recess 13 which permits each knuckle to embrace a post 7, the receptacle being clamped upon the base in an obvious manner by means of thumb-nuts 14. In the form illustrated I'have shown the knuckles reversed on opposite sides so that the re- :eptacle may be swung about readily on the base. This and other details of construction are, however, being obvious that there may be many vamcrely preferred forms, it-

riations in the form, shape and size of such incidental parts. \Vithin the receptacle 8 and secured to or integral with the bottom 10 of the receptacle are a series of conical radiator pins 15. These radiator pins are substantially semicircular and are hollow and open except at the top where they are closed by a cap. That is to say, when the vulcanizer is turned on its side these radiating members are substantially conical troughs. Those pins constitute a preferred form of a heat distributing member which in the vertical position of the vulcanizcr provide for the uniform distribution through the bottom of the receptacle of the heat imparted by the flames of the fluent or liquid fuel, which is indicatedby dotted lines on the bottom of the receptacle 8 as shown in Fig. i The heat distrilmting members also themselves constitute fuel receptacles when the apparatus is applied as indicated, for cxample, in Fig. 3, where the fuel is shown in the two heat distrilmting members which for convenience are illustrated in section.

16 represents .a rubber tube clamped against the bottom of the receptacle 8.

17 represents a rubber patch in place and 1.8 represents the pumictur'e or center of a cut in the tire. In this (use an additional amount of soft or quiclccuring rubber, such as is used in this repair work, is indicated at the point 18. I

In Fig. 3, as before stated, I illustrate the vulcanizer as applied, for example, to the tread of a tire in place on a wheel, a chain for the purpose of holding the vulcanizor in It is obvious,

place being also indicated.

securing device however, that any suitable may be employed.

In using, the apparatus in the vertical po sition, as illustrated in Figs. 1. and '2, 1 put a certain quantity of fuel, preferably cast lcnc, in the bottom of the rcceptzuzle. \Vhcn the fuel is'ignitcd the flames will heal not only the walls of the receptacle but also the heat distributing members and while the bottom of the receptacle 8 is protected from too great direct heat being. applied, those members conduct the heat of the flames down through the gasolcne and the bottom of the receptacle and distribute it uniformly throughout the bottom and to all theparts of the patch and a constant determined temierature is maintained vbich cannot in any instance injure the already vulcanized ar 2,, a somewhat larger quunti troughs throughout the trough so that each ti'ough will be supplied icicle,

In Fig. 2 I have shown two dotted lines above the vulcunizei: to indicate the manner in which the heat is :iegulutecl. E i heo the gasolene is first ignited the flames will higher and higher the heat increases and by permitting the inflow of ascending or and by raising the Zone of combustion alcove t; i heat conducting members will serve to automatically lower the tempera ture until this lowered temperature permits: the flame to again sink to 3. lower level cool ll Toe seen that the trough pine belie passing through eoeoeoe receptacle until ll the liquicl :i uelwis con i vhile I have illustrated the heat rlietirio lit-in members 15 substout-iellv SGl'Ill-ClE-w.
